Among other uses, latexes are a successful alternative to solvent-borne binders for coatings. Efforts are made to produce hybrid nanostructured latexes containing an acrylic phase and an alkyd phase. However, after the film-forming process, the surfactant used to stabilize these latexes remains in the film, and its location can have a drastic effect on the application properties. Among the proc...

Hybrids made from an alkyd resin and an acrylic copolymer can potentially combine the desired properties of each component. Alkyd/acrylic hybrid latex particles were synthesized via miniemulsion polymerization and used to create films at room temperature. Comparisons of the alkyd auto-oxidative cross-linking rates and the associated network development are made between two alkyd resins (with di...

Alkyd resin was prepared from shear butter oil (SBO) using the two step procedures; alcoholysis and polyesterification. The oil and alkyd resin were characterized and evaluated by standard methods, for their physico-chemical properties. The analysis showed that the alkyd resin based on Shea butter oil recorded average acid value of 15.2 (mgNaOH/g), iodine value (98.0 mg/g), P value 6.7, density...

Purpose: Alkyd resins constitute a very high proportion of conventional binders used in surface coatings. In order to enhance the quality of these alkyd resins methyl esters of rubber seed oil (MERSO) were used in the preparation of the resins. Methods: MERSO were obtained by in-situ alcoholysis of rubber seed. Alkyd resins having oil lengths of 45, 50 and 55% were prepared with MERSO, phthalic...

This paper reports findings of a study of a batch chemical process using simulation. A model of an alkyd resin plant is presented and used to carry out improvement studies, to evaluate changes in plant operating conditions. With the proposed changes, in the simulation studies, productivity could be improved to around ten percent. Key-Words: Monte Carlo simulation, alkyd process modeling, probab...

The usage of edible oils for alkyd resin synthesis has lately been of great concern because they can alter the food chain. Research is on the forefront on the oils that are considerably available and do not compete with food sources. Thus, the viability of preparing alkyd resin from inedible, non-drying gmelina seed oil (GSO) was investigated. The physico-chemical properties (viscosity, iod...

Alkyd resins are amongst the most important and widely used resins in coating sectors. In this communication we report on preparation of alkyd resins emulsified by grafted acrylic resins on their fatty acid moieties. Both high-shear mechanical homogenizer and ultra-sonic sonicator were used step-wise to disperse the alkyd resin and acrylic based monomers in aqueous media. The resins are of nano...

alkyd resins were prepared into four different sets by varying the percentage concentrationof the glycerol content. various properties such as the viscosity, surface drying time, solubilityand color of the alkyd resins were evaluated for the various sets. the alkyd resin with the highestglycerol content was the most viscous, brownish in color and having the highest molecularweight this is due t...
